The Department of Environment and Natural Resources (DENR) Mines and Geosciences Bureau IX (MGB) has already completed 21 geohazard maps for 21 municipalities for Region 9 from 2011 to present.

OIC Geosciences Division, MGB IX Vheina Marie P. Quintana, revealed during an interview that the office already finished and distributed 21 geohazard maps for the entire region 9

For 2011, the office finished mapping at Aurora, Zamboanga del Sur, Dipolog City, Zamboanga del Norte, Pagadian City, Zamboanga del Sur, Kumalarang, Zamboanga del Sur, Tungawan, Zamboanga Sibugay, Buug, Zamboanga Sibugay, Imelda, Zamboanga Sibugay, Dapitan City, Zamboanga del Norte, and Ipil, Municipality.

For 2013, Tambulig, Zamboanga del Sur, Polanco, Zamboanga del Norte, Titay, Zamboanga Sibugay, and Ramon Magsaysay.

The office is scheduled to go to Salug, Zamboanga del Norte this July where they will target 23 barangays.

The office started their mapping last January 2011 and they are targeting to finish their mapping by December 2014.

The Geohazard Map which the office is doing is magnified which is 1 is to 10,000. The earlier Geohazard Map done from 2006 to 2010 is only 1 is to 50,000.

Quintana said that they already finished the maps of 21 municipalities out of the 72 and they already distributed the finished maps to the mayors and other concerned agencies in the area.

Because of the deadline, the MGB Manila has outsourced, technical consultant to assure that the Geohazard Mapping will be finished on time. Aside from this, mining permitees in this region will also do their respective Geohazard Mapping in their respective areas.

According to Quintana, the target of the office is eight municipalities per year where the MGB Region IX only has two geologist Quintana and Mustansir V. Manjoorsa.

Because of this, she has said that there is a possibility that the maps might not be finished by 2014 eventhough there will be outsourcing.

The Geohazard Mapping is being done due to climate change and the several disasters happening in the whole country. This is one of the programs of the national government when it comes to disaster preparedness.

The office has a budget of P1.8 Million for the eight municipalities for the Geohazard Mapping. During the Geohazard Mapping, the Geologist checks the surroundings, the location, if there are rivers, mountains and other aspects.

The objective of the office is to come up with a Geohazard (Landslide and Flood Susceptibility) Map of Zamboanga Peninsula.

The Geohazard Map could be used by national agencies, Local Government Units (LGU’s), urban and rural development planners, stakeholders, and communities as guide on their disaster risk management plans and programs for the protection and preservation of the community, property, government, and private infrastructure from these geologic hazards.

The map will also inform the local populace of their susceptibility to geologic hazards in order for them to be prepared and equipped when faced with natural disasters and to save lives and be proactive for any eventualities.
